Headphone Amplifiers

Product Description

The headphone amplifier is designed around single or dual-channel op-amps such as Burr-Brown's OPA2134 or OPA2132PA, however, a wide variety of op-amps have been successfully implemented. The amplifier's design is quite simple. It consists of only a few components, can be assembled on a small section of protoboard, has a lower parts cost than other headphone amplifiers, and can run for many hours on a single 9 volt battery. In spite of this, a well-made CMoy amplifier can drive even demanding headphones, like Sennheiser's HD600 or low impedance Grados quite well.
